Used extensively in organic synthesis as a chiral building block for pharmaceuticals, particularly in the production of enantiomerically pure compounds. It serves as a key intermediate in the synthesis of various active pharmaceutical ingredients (APIs), especially those requiring stereochemical control. The compound is also employed in peptide coupling reactions, where it acts as a protecting group for carboxylic acids, ensuring selective reactions in complex molecular assemblies. Additionally, it is utilized in the development of biologically active molecules, including enzyme inhibitors and receptor modulators, due to its ability to introduce specific stereochemistry and functional groups. Its application extends to material science, where it is used in the preparation of chiral polymers and advanced functional materials.
